UNITED Application filed June 10 1907. filerial 1%;378066. R

T 0 all whom it may concern: Be it known that 1, Moses W. Kern-vs, a citizen of the United tates, residing all Golumbus, in the county of Franklin and State of Ohio, have invented certain new and use ful Improvements in Reversing lvlechauisin, of which the follmving is a specification, rot erence being had therein to the accompa nying drawings.

he present invention relates to reversing mechanism, and is designed more particularly for use with gasolene traction engines.

The object of the in'vention'is to provi'i'le a reversing mechanism of this character whicl: Wlll impose a mlnimum amount of strain upon the engine and: the driving connections when the same are re ersed: hich will be practically noiseless in operation; and which, when the driving mechanism is moving in a forward direction, will be motionless Afurther object of the invention is to provide suitable means for operating said versing mechanism. With these objects in view my invei consists in certain novel of cons-tr tion and in certain. parts and comhinati hereinafter to be described, and then more.

fully pointed out in the claims.

In the accompanying drawings, Figure l is a top plan view of a portion of a traction engine embodying my invention; Fig. 2 is a sectional view of the same showing the reversing mechanism in elevation; Fig. 3 a top plan view of the reversing mechanism, partly in section; Fig. 4 is a detail view showing the operating mechanism therefor; F 1g. 5 IS a detail sectional view of the compensating gearln these drawings, I have illustrated the preferred form of my invention, sh owing the same as embodied in a gasolene traction engine of a known construction and comprising a frame 1, adapted to support an explosive engine, which is not shown, and also to sun port a crank shaft 2, to which. said engine connected. This shaft is divided on one side of the frame and the two portions connect- As here shown, this division is accomplished by mounting a sleeve 3 upon the outer end of the shaft and providing the same with a clutch member 4, adapted to cooperate with the second clutch member 5 wl'iich secured to the shaft 2. Mounted on the sleeve 3 and adapted to slide freely thereon and to rotate S lhei fllltil MOSES W.

The pinion 13 is preferably of falength equal to approf-ziniate 3 he coml)ined Width; of the gear 2 and the pinion (i. ll hHSm-vhen the pinion 6 moved to its outer positiom and the intern Tate pinion l3 to-itsinnerwso most position, the intermediate pinion. will; mesh with both the gear 7 and thepi-nionfi thus driving the 7 in a reverse directionr to that in which it is driven when in direct 11': engagement with the pinion 6. The I ar -8,5 rangement of these pinions may, of course; to adapt. the same to special-cine cumstances, but 1- refer the arrangementh herein shown and rave provided suitable operating mechanism for shifting lZllQwPlIl 229D ions when they are mounted, herein shown; This operating mechanism of a lever' 16, pivoted atl?" to asuitahle portion ol'z thc frame 1 and provided with a suitalileyoliem 38 at one end adapted to engage the'groioved ,95 collar 1.9 which secured to thepxriionfit. The opposite end of the lever 16 provideds with an elongated slot 20, through. whichexei tends a lever 2i, which connectcdmtowthen a universal jointi22=arid 1,00 is provided at its opposite end v "1h 'aisiuiahle handle A rod. 24 is pivot-allycon-i nected to thelever 21 at a point intermediate its ends and is pivotally connected atiits cp w 'posite end to the arm 25 of a bell cranlclever': 26 which is pivo tally connected to the frame",

as shown at The other arm 28 of the belly crank lever is provided with a yoke ,2 9;- adapted to enga e grooved collar 30 whiclr is secured to tne intermediate pinion 13.;11'0

Thus, it will be seen that when the lever 21 is moved about its pivotal center in a horizontal plane, the lever 16 will be rocked about into enga ement with the intermediate pinion 13. It will also be seen that when the lever 21 is moved about its-pivotal center in a vertical plane, the arm 24 will rock the bell crank lever 26 about its pivotal center and move the intermediate pinion 13 longitudinally of its supporting shaft and move the same into or out of en agement with the gear 7. A suitable gui e 32 may be pro- 'vided for controlling the movements of the 'handle 21 so as to properly time the shift ng of the two inions. T is guide is here shown as comprising a transverse portion 33 extending in front of the lever 21 and preventing the same from l-eing moved forwardly until it has been moved laterally a distance sufficient to move the pinion 6 entirely out of mesh with the gear 7. At this point the guide is provided with a forwardly extending portion 34 which permits the forward movement of the lever a distance sufficient to move the intermediate pinion 13 into mesh with the gear 7 and serving to prevent the lalteral movement of the lever 21 in such a manner as to move the inion 6 into engage ment with the gear 7 w ile the intermediate inion 13 is in mesh with that gear.

Thus, it will be seen that I have provided a. reversing mechanism which, when the traction engine is moving in a forward direction, is stationary, and which can be readily operated to reverse the direction of movement of the driving connections without imposing any considerable amount of strain upon said connections or upon the engine; that'the mechanism is of such a-character that when in operation the noise will be re duced to a minimum or entirely eliminated; and further, that I have provided a suitable mechanism for operating the reversin mechanism which'is so controlled that the pinions move into and out of engagement with the gear at the proper time, as determined by the movement of the other pinion.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure Letters Patent, isz- 1. In a traction engine, the combination,

with a driven shaft, a driven gear, a com pensating gearing connecting said gear to said. shaft, av crank shaft and a pinion sl'idably mounted thereon and adapted to be moved into and out of engagement with said gear, of an intermediate pinion adapted to be moved into engagement with b oth said gear and said pinion when said gear and said pinion are out of'engagement one with the other.
